Patterning

Patterning is a critical technology that enables precise micro- and sub-micron scale structuring of optical surfaces, essential for controlling light in imaging, sensing, display, and photonics applications. By delivering high-resolution, low-defect patterns combined with advanced coatings, Materion enhances optical device performance and reliability across diverse industries.

Materion offers a comprehensive portfolio of patterning solutions designed for exceptional precision, durability, and spectral control.

Sub-Micron Patterning

Our sub-micron patterning capabilities produce features as small as 500 nm with tight tolerances and minimal defects. Integrated with multi-material stacks and advanced coatings, these patterns support calibration targets, beam shaping, reticles, and projection optics. Absorptive and reflective materials such as black chrome, chrome, and silver ensure high contrast and optical efficiency.

Micro-Patterned Optical Filters

Using a novel plasma-assisted reactive magnetron sputtering (PARMS) process, Materion fabricates high-thickness, patterned dielectric filter stacks with extremely steep spectral edges and broadband blocking. These filters deliver over 90% transmittance, outstanding environmental stability, and customizable dimensions, ideal for hyperspectral imaging, Raman spectroscopy, and automated sorting.

Patterned Chrome

Materion’s patterned chrome coatings provide opaque, low-reflectance, and high-resolution patterns optimized for optical and semiconductor applications. With excellent adhesion and low pinhole density, these patterns are used for apertures in microdisplays, masking filters, photolithography masks, and alignment marks.

Patterned Dichroic Filters

Our patterned dichroic filters integrate multiple spectral filters on a single substrate using advanced photolithography and plasma-assisted deposition. This monolithic approach eliminates assembly, reduces thickness, and ensures high spectral performance with low cross talk. Applications include multi-spectral imaging, color sensors, lighting, and space-qualified optics.

With precise control over pattern dimensions, materials, and coatings, Materion Patterning Solutions delivers the perfect balance of performance and reliability.

Whether you need ultra-fine calibration targets, high-performance spectral filters, or durable patterned coatings, Materion helps you shape light with unmatched precision.
